GLASP-FASTENER.

Specification of Letters Patent.

Patented Dec. 9, 1919.

Application filed June 17, 1918. Serial No. 240,279.

To all whom it may concern:

Be it known that I, KIYOSHI IBUsUKI, a subject of the Emperor of Japan, residing at Kansas City, in the county of Jackson and the State of Missouri, have invented certain new and useful Improvements in Clasp-Fasteners, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to clasp fasteners for fastening .shoes, gloves, leggings, belts and the like.

Clasp fasteners are not new, but the ordinary clasp in general use soon becomes loose and often becomes disconnected. It is essential that a clasp fastener be provided that will not become loose and disconnected.

The present invention has provided a clasp fastener combined with a positive retaining means to support the strain tending to unfasten and disconnect so that the clasp will remain connected until it is purposely disconnected.

With these and other objects in view, the invention consists in the features of construction, combinations and arrangements of parts hereinafter set forth and more particularly pointed out in the appended claim, the accompanying drawings illustrating a form of the improved clasp fastener.

In the drawings Figure 1 is a face view of the improved clasp fastener connected.

Fig. 2 is a face view of the inner clasp fastener member.

Fig. 3 is an end view of the inner clasp fastener member.

Fig. 4 is a face view of the outer clasp fastener member and the retaining plate.

Fig. 5 is a sectional view taken on line 55 of Fig. 1.

The views Figs. 1 and 2 represent the clasp fastener attached to an article, as a shoe, glove, legging, belt or the like, 1 being the inner overlapping wall, 2 the lining of the inner overlapping wall, and 3 the outer overlapping wall, the overlapping walls being common to shoes, gloves, leggings, belts and the like.

The inner clasp fastener plate 4 is provided with the prongs 5 preferably integral therewith, the prongs being inserted through the wall 1 and clenched as shown in Fig. 3, securely fastening the plate to the wall.

The inner plate 4 1s provided with the plunger holes 6, and the rectangular holes 7 forming the transverse bars 8, the inner wall 1 being cut away underneath the transverse bars to make room for the hook 9 of the outer clasp fastener plate 10, the hook being preferably integral with the plate.

The outer clasp fastener plate 10, is secured t0 the outer wall 3 by the rivet 11 and retaining plate 12, and the integral prong 13 which is inserted through the wall and clenched as shown in Fig. 5.

The plate 10 is provided with the plunger 14 preferably integral with the plate and of a size to snap into the plunger holes 6, sufficiently tight to retain the plunger in the hole, but not so tight but what it can be easily withdrawn by a direct pull at approximately a right angle to the plates 4 and 10.

'It will be noticed that the hook 14 as shown in Fig. 5 is resting against one of the transverse bars 8, and all of the strain tending to separate the walls 1 and 3 is sustained by the bar and hook, the plunger 14 being employed merely to retain the overlapping walls close together as shown so that the hook will receive all the bursting strain tending to separate the walls.

By removing the plunger from the hole 6 the hook may be easily disengaged from the bar 8, and the hook is easily engaged with either of the bars when the plunger is withdrawn from the hole, it being understood that the hook may be engaged with either of the transverse bars 8, and the plunger inserted in the corresponding holes 6, so that the clasp fastener is adjustable as well as very secure when fastened.

What I claim as new, and desire to secure by Letters Patent, is

In a clasp fastener, a plate, a plurality of transversely disposed round bars in said plate, a plurality of plunger holes in said plate, a second plate, a hook on said second plate, a clasp plunger on said second plate, and the hook on said plate formed by a slotted opening facing from said clasp plunger so that said hook may be engaged with one of said bars when said second plate is approximately at a right angle to said first mentioned plate and said second mentioned plate pressed to alineinent with said first mentioned plate and the clasp plunger engaged with one of said plunger holes to hold said hook securely engaged with the respective bar.
